Design a class named MyInteger. The class contains:
A????1 An int instance variable named value that stores the int value represented by the object.
A????1 A constructor that creates a MyInteger object for the specified int value.
A????1 A get method that returns the int value.
A????1 Static methods isEven(int), isOdd(int) and isPrime(int) that return true if the specified value is odd, even, or
prime, respectively, and false otherwise.
A????1 Methods isEven(), isOdd(), and isPrime() that return true if the value in this object is even, odd or prime,
respectively, and false otherwise.
A????1 Static methods isEven(MyInteger), isOdd(MyInteger) and isPrime(MyInteger) that return true if the value of
the specified object is even, odd, or prime, respectively, and false otherwise.
A????1 Method equals(int) that returns true if the value in this object is equal to the specified integer.
A????1 Method equals(MyInteger) that return true if the value in this object is equal to the value in another object.
A????1 Static method parseInt(char[]) that converts an array of numeric characters to an int value.
A????1 Static method parseInt(String) that converts a string into an int value.
Note: if c is a character from A????10A????1 to A????19A????1, then (int)c-48 converts c to an integer value.
You may assume that the user enters only digits.
HereA????1s a demo class that tests the above methods and the output. Use a similar demo class.
public class MyIntegerDemo
{
public static void main(String[] args)
{
MyInteger n1 = new MyInteger(5);
System.out.println("n1 is " + n1.getValue());
System.out.println("n1 is even? " + n1.isEven());
System.out.println("n1 is odd? " + n1.isOdd());
System.out.println("n1 is prime? " + n1.isPrime());
System.out.println("15 is prime? " + MyInteger.isPrime(15));
char[] chars = {'3','5','3','9'};
System.out.println(MyInteger.parseInt(chars));
String s = "9786";
System.out.println(MyInteger.parseInt(s));
MyInteger n2 = new MyInteger(24);
System.out.println("n2 is " + n2.getValue());
System.out.println("n2 is odd? " + n2.isOdd());
System.out.println("45 is odd? " + MyInteger.isOdd(45));
System.out.println("n1 is equal to n2? " + n1.equals(n2));
System.out.println("n1 is equal to 5? " + n1.equals(5));
}
}
